[6.x]: {% js %} blocks do not execute within custom plugin widgets. #19088

What happened?

Description

i noticed that {% js %} blocks in widget Twig templates that worked in Craft 5 no longer execute for custom plugin widgets in Craft 6.

Example:

    alert('test');
{% endjs %}

Expected behavior

the script should be registered/executed
